TiledLib.Net

Cross-platform Tiled map parsing utilities.

Nugets

TiledLib - Core library, everything you need to read Tiled maps/tilesets.
TiledLib.Pipeline - MonoGame content pipeline extension, provides a ContentImporter for Tiled maps. If you add a ContentProcessor, you will be able to map the output of the supplied importer to custom classes tailored specifically for your game.

Basic usecase

using (var stream = File.OpenRead(filename))
{
    var map = Map.FromStream(stream, ts => File.OpenRead(Path.Combine(Path.GetDirectoryName(filename), ts.Source)));

    foreach (var layer in map.Layers.OfType<TileLayer>())
    {
        for (int y = 0, i = 0; y < layer.Height; y++)
            for (int x = 0; x < layer.Width; x++, i++)
            {
                var gid = layer.data[i];
                if (gid == 0)
                    continue;

                var tileset = map.Tilesets.Single(ts => gid >= ts.FirstGid && ts.FirstGid + ts.TileCount > gid);
                var tile = tileset[gid];

                // Do stuff with the tile.
            }
    }
}
